Horizontal Pumps
Designed and meant to be used as a horizontally mounted assembly.
This includes feet on the pump, motor or both for securing the pump
and motor to its floor or structure. The most common type of
Horizontal pump is the End Suction, where the fluid enters the
front end of the casing and exits perpendicularly. The source of
liquid is either above the pump, in which case it is a positive
head and no special priming is needed. If the liquid source is
below the pump then either a priming chamber is needed or use of
some sort of suction side valve, i.e. foot valve, to maintain prime
in an open pumping system. If the inlet and outlet go into the same
tank, i.e. re-circulating or filtering, and the lines are kept
below the surface level, then after initial priming the system will
maintain its prime.The two big considerations that must be given to
horizontal pumps is priming method and NPSHa.Typical Centrifugal
Horizontal pumps include mechanically sealed, magnetic coupled
seal-less, self-priming, multistage, jet, back pullout, portable,
API and ANSI to name a few.
